Freezing points; we all know how it works. When two different materials are together, this works to your advantage. For instance - tar based sound deadening on metal. If you get the surface cold enough, it will simply shatter the deadening away.

To do this, basic cryogenics will do. I’d never really worked with dry ice before, and immediately I had a respect for how cold it was. Just grabbing the bag without paying attention my hand stuck to it. This stuff is COLD.

Within seconds you could hear a popping and crackling sound and it was really cool! After a few minutes we went to work with a soft faced hammer and began our work bit by bit. Nathan took the hatch area and I took the front. Here’s what we got.

Once we finished the job of sweeping it all out and rounding it all up, we weighed it all. With the rubber firewall insulator included it was 53.2 pounds shaved. Not bad at all I’d say.

So I can say first hand the dry ice trick does work, and works well. Bonus laughs because there were a few bolts inside the car that turned solid white from the cold. Science is something I’ve always loved.

Doing this wouldn’t damage any of the metal from it being warm, then sudden extreme cold and then warm again, would it...?

Nope not at all :) everything worked wonderfully. The garage temp is low 40s so there wasn’t a huge spike to hot either. It just made the task at hand hilariously easy and almost entertaining.

It’s an old school trick the DSM community has used for a long time and I’ve always wanted to do it haha

53 labs?!? That is insane. What a nice savings
